ABSTRACT:
A surface acoustic wave filter has an input electrode and an output electrode of a finger type with mutually parallel elongated fingers formed generally at a constant pitch on a piezoelectric substrate and sandwiched between a pair of reflectors. Two of these fingers of the input electrode which are the closest and the second closest to the output electrode, or two of these fingers of the output electrode which are the closest and the second closest to the input electrode, are connected together to a same grounding terminal. A plurality of such filters may be connected together to form a multi-stage filter.
